Just as a follow up to the above, my rifle came in and I've had a day to mess around with it. The rifle itself is an excellent purchase, well thought out and secure. The CA forearm fully supports the longer barrel. However, it'll take some time before the aftermarket guys get their acts together. I bought the G&P forearm in order to get the bipod, but that forearm does not include the supports for the longer barrel...meaning that the barrel is solely relying on the threads at the end to hold it formly in place. To its credit, the barrel does lock firmly in place and it's unlikely that I'll ever have to worry about it, but it'd be nice to have it supported at the front as well. I'll rig something up for now. I love the bipod on the G&P forearm. The CA carry handle is a very nice build. Solid and clean and the optice actually serve a purpose. The lenses are clear and the amplification is worthwhile, and far and away superior to the old Dragon kits. The full length stock is nice for guys like me who have longer arms, too.
Overall I have no complaints with the rifle itself and only minor ones with the aftermarket parts, all of which can be dealt with.
